DEVICE GENERATING GAS FOR 'USE IN INTERNAL-COLJIBUSTQON ENGINES.'

Specification of Letters Patent.

Patented Dec. le, MM5.

i Application filed May 2.5, i914.4 Serial No. 840,892.

, l which the following is a specification.

' My inyention relates to a` device for generating gas from crude oil for use in intern'al combustion engines, and its object is to readily extract all the combustible gases from such crude oil, to keep such gases in a gaseous state until it reaches the compression chamberand for other purposes w ich will hereinafter more fully appear.l

In the drawing accompanying my speciiication Figure lrepresents a sectional view of the gas generator complete. Fig. 2 is a sectional view along line c on Fig. l.

In said drawing 2 is an outer casing.

2l is a cap adapted to close the upper end of such outer casing and 22 is a cap adapted to close the lower end of the outer casing and to be easily removable.

Outer casing has an opening 23 on one side inA the form of a. tube running at an acute angle from the wall of the outer casing and pointing upward. rlChis ytube can be constructed integral with outer casing 2.

24 is an air chamber encircling outer chamber 2. l

25 are openings through the wall of air chamber 2l to admit air to the inside oi? such chamber. i

3l is an exhaust port.

3 is a lead connecting` exhaust port .3l with opening 23.

32 is an air chamber encircling lead 3, and 33 are openings into air chamber 32, the purpose Yof which will hereafter more readily appear.

Il is an inner tube adapted to lit into outer casing 2 with an air space 4:1 between the inner tube and outer casing. Tube is preterably constructed ot metal.

43 is a cap which fits neatly over the upper endl ot' tube 4, and 42 is a cap which lits over the lower end. Cap 42 has a depending hollow projection i6 which is fitted to rotate in a bearing 26 in cap 22.

f At thc end ot' hollow projection 4G I have placed a valve-5, the object of which is to permit the discharge of the refuse which is extracted from the gas producing elements injected into the inner tube 2. Valve 5 consists of a T member, the upper end of which rests in a seat 52 at the lower end of hollow projection 46, which end is open.' rJ'his valve is held in a normally closed position by G0 means of a spring 53. 5st is an opening through the wall of cap 22, and is constructed to allow the refuse to pass through when valve 5 is pressed down suiiciently to permit opening 54 to communicate with hollow 65 extension sin. Cap a3 has a hollow extension 48 which is adapted to rotate in a bearing 2?. Hollow extensions 46 and 48 are on linc when the generator is assembled,the object being to permit the inner tube to be rotated within the outer casing.

6 is a. wheel attached to extension 4S being adapted to transmit power ,'for rotating caps i3 and 4:2 and th'e inner tube si. `In my construction I hare lnner tube -vlA iitted neatly into caps and 43, so the generator is f pproximately gas proof. It is well knownI that gas generators which use crude o iilf/ readilyI become incrusted with the retusef from the oil and the construction herein y above referred to permits the inner tube 4 to be readily removed by loosening bolts 28 and removing Acaps 22 and 42, when a clean inner tube can be readily inserted.

ll is a member which lits at a running tit the opening in projection 48. Member 1l is.l hollow :and closed at the top with cap 9 which can be constructed integral with member 1l.

l2 is the conductor from member 11 tothe 90 compression chamber' of the engine and is covered with heat non-conducting material.

8 is a lead which carries the crude oil to j the interior ot' the inner tube and the flow ot the oil Iis regulated by means or' a valve 95 strikes inner tube el, and tl'ieret'ore at its hot- 100 test portion. In installing this gas generator have inclined it at an angle of approximately degrees. It will be observed that as the crude oil is deposited on the interior of the inner tube, with the innertube rotating' 105 and leaning at an angle from the perpendicular the oil will slowly spread over the interor of the inner tube and low toward the eyhaust port bottom of such tube, and as the tube is kept warm by the hot air from the exhaust ports the gases in the crude oil are released.

49 is an opening in the wall of outer casing and is adapted to ca"ry oill the burnt gases which pass into the space 41 from the 81. This opening (49) should be above cap 22 so cap 22 can be more easily removed. It is further observed thatl the residue of the crude'oil atter the release of gas therefrom carbonizes more readily on the inner tube than crude oil in its natural state. To meet this I have first applied the heat from the exhaust port of such innei tube and deflected it downward.

10 is a bracket attached to outer casing 4, adapted to hold member 11.

To supply hot air to the interior of the inner tube I have run a pipe from air chamber 32 to the interior of inner tube 4. 7 is a lead for the purpose of injecting water into the inner tube. By means o't' a valve 71 or other devices in common use the amount of water and air admitted to the inner tube can be regulated so the mixture will produce gas of high efficiency. Leads 7, 8, and pipe 8l are inserted into inner tube 1 through member 11.

It is further to' be noted that low grade gas sometimes liquefies in passing from the n gas generator to the intake on the cylinder. T o overcome this objection I have connected pipe 13 with air chamber 24, and to intake pipe 12 for the purpose of drawing the hot air surrounding outer casing Q into the mixture. The amount of air thus admitted can be regulated-by a valve 17 or by any means now in use for such purposes.

'hat I claim as my invention for which I des-ire Letters Patent is: y

i.. In a crude oil gasifier for an internal combustion engine, a casing, an inclined tube within the casing and separated therefrom to form a heating space, means for supplying heat to such heating space, closures at each end of such tube, means for rotating the tube in said casing, means for supplying fuel at the upper end of such inclined tube, means for conducting gas from such inclined tube, and means for discharging fuel refuse from such inclined tube con sisting of an outlet in the lower part of such tube. a vvalve constructed to normally close such outlet, and when Weight is placed there on from within such tube, to open such outlet, all substantially as described.

2. In a gasiiier for an internal combustion engine, for using crude oil as fuel, an inclined outer casing, an inclined rotary tube therein separated 'fromi the outer cafing to provide a heating chamber between such outer casing and such tube, a pipe attached to such outer casirg at an oblique angle thereto pointing downward, communicating with the `inside of such outer casing, and constructed to conduct heating fluid to the heating chamber between such outer casing and-such inner chamber, and to deflect such heat downward, an outlet for such heating .'luid through such outer casing near the 'lower end thereof and through the portioirof the wall opposite to where such heating fluid i conducted into such heating chamber, outside means for rotating such inner chamber, means for depositing such crude oil within such inner chamber upon the inside wall and near the top thereof, aud means for conducting gas from such chamber.
